Building the Tile

git submodule update --recursive --init
docker run -v $(pwd):/work -ti weaveworks/p-weave-builder $TILE_VERSION_NUMBER

Specify $TILE_VERSION_NUMBER as, for example, 0.0.1.

This builds a tile (.pivotal file), which is the artifact which you can upload to ops manager.

Building the tile builder Docker image locally:

docker build -t p-weave-builder .
docker run -v $(pwd):/work -ti p-weave-builder 0.0.1

p-weave's Issues

Improve README

It would be great if the README answered the question "what is this and why should I care?" really well and included some screenshots :)

docs: p-weave does not provide a service broker

In quite a few places the docs refer to a Weave Cloud Service Broker that creates services. That's not correct. There's no service broker and there are no services included in this tile. Those terms have a very specific meaning in the context of Cloud Foundry (see https://docs.cloudfoundry.org/services/overview.html if you're interested).

What this tile really does is to:

• collocate the Weave Cloud agent on all VMs inside the ERT deployment
• deploy an instance of Prometheus that is configured to scrape the CF API, CF Firehose, and the BOSH API, and forward all of those metrics to Weave Cloud

@stefanprodan + @ngehani: Would you mind clarifying this in the docs? I believe this will also help with your upcoming demos and user validation.

Container CPU and Network stats reporting incorrectly

Focusing on CPU: the numbers for CPU are a little "buggy," showing values like 348 (where one would expect a percentage in the range of 0-100. May be showing CPU time rather than percentage.

This impacts, for example, the waterline overlay rendering on the Explore containers.
